A Simple Guide for Restaurant Owners and Commercial Kitchens
If you run a restaurant, café, or any type of food business, then you’ve probably heard of something called a grease trap. This important piece of equipment is often hidden under your sinks or floors, but it plays a big role in keeping your kitchen and plumbing working properly.
Over time, your grease trap gets full of fats, oils, and grease—often called “FOG” in the industry. When that happens, you’ll need a professional grease trap cleaning service to step in.
But what exactly happens during this cleaning? How do the professionals do it? And why is it so important?
Let’s explore everything you need to know in plain, everyday language.
What Is a Grease Trap and Why Is It Needed?
Its job is simple: catch fats, oils, and grease before they enter the sewer system. These greasy materials come from dishwashing, cooking, and cleaning.
Why Can’t Grease Go Down the Drain?
Grease might go down as a liquid, but it hardens as it cools. When that happens inside your pipes, it can cause:
- Blocked drains
- Bad smells
- Slow water flow
- Damage to your plumbing
- Fines from local health or environmental departments
Grease + Pipes = Big Problems
If too much grease enters the public sewer system, it can cause huge blockages known as fatbergs.
Why Is Grease Trap Cleaning Important?
Grease trap cleaning isn’t just about keeping things tidy—it’s essential to keep your kitchen running smoothly and legally.
It’s Required by Law in Most Places
Most cities and towns require commercial kitchens to clean their grease traps regularly. If you don’t, you could face:
- Health code violations
- Fines from city inspectors
- Forced closure of your business
Cleaning Frequency
Depending on the size of your trap and how busy your kitchen is, you might need cleaning every 1 to 3 months.
It Prevents Bad Odors and Overflows
When grease builds up, it begins to rot and smell. This can spread unpleasant odors throughout your kitchen—and even into the dining area.
Overflow = Major Cleanup
If the trap gets too full, it can overflow, pushing grease and sludge back into your sinks, floors, or drains. Cleaning up after that can be a real mess—and very expensive.
How Does a Grease Trap Cleaning Service Actually Work?
Now let’s get to the heart of it—how does the service work from start to finish? Here’s a simple, step-by-step explanation of what you can expect when you hire professionals to clean your grease trap.
Step 1 – Inspection and Preparation
The service team will begin by inspecting your grease trap to see how full it is and what kind of condition it’s in. They may also check for signs of damage or leakage.
Safety First
They’ll make sure all safety procedures are followed, such as wearing gloves, goggles, and protective gear. Grease trap waste can be toxic and full of bacteria.
Step 2 – Pumping Out the Grease Trap
The team will use a vacuum truck or pump to suck out all the waste materials from the trap. This includes:
- Fats, oils, and grease (the top layer)
- Food solids and sludge (the bottom layer)
- Dirty water (the middle layer)
What’s Left Behind
Without cleaning, these layers harden and reduce the trap’s ability to work properly.
Step 3 – Scrubbing and Deep Cleaning
After the trap is emptied, the team will scrub the inside walls and baffles of the grease trap. This helps remove:
- Hard, stuck-on grease
- Smelly buildup
- Any leftover debris
No Shortcuts Here
A good cleaning service doesn’t just pump and go. They clean the trap fully so it works like new.
Step 4 – Final Inspection and Report
Once the cleaning is done, the technician will:
- Reinspect the trap
- Check for damage or clogs
- Make sure everything is working properly
- Record the service in a log (sometimes required by law)
Proof of Service
Most professional companies will give you a report for your records. This is helpful if you need to show compliance with health codes or inspections.
What Tools and Equipment Do Professionals Use?
Professional grease trap cleaning companies use special tools to do the job safely and thoroughly. Some of these tools include:
Hand Tools and Scrapers
Technicians use heavy-duty scrapers, brushes, and rods to clean the walls and hard-to-reach areas inside the trap.
Safe Cleaning Solutions
In some cases, they’ll use non-toxic, eco-friendly cleaners to help remove odors and clean the inside without damaging your plumbing.
How Often Should You Schedule Grease Trap Cleaning?
The cleaning schedule depends on several factors:
1. Size of the Trap
Larger traps can hold more waste, so they may need cleaning less often. Smaller traps fill up quickly and need more frequent service.
2. Volume of Cooking
Busy kitchens that fry, grill, or prepare greasy foods will create more grease. These businesses may need cleaning every 30 days.
3. Local Regulations
Many cities have laws that require cleaning every 90 days at minimum. Be sure to check with your local health department.
Frequently Asked Questions About Grease Trap Cleaning Services
Can I Clean My Grease Trap Myself?
For small under-sink traps, some restaurant owners do clean them on their own. But for larger or in-ground traps, it’s strongly recommended to hire a professional. The waste needs to be disposed of properly, and cleaning without the right tools is unsafe.

Grease trap cleaning costs can range from $100 to $500+, depending on:
- Size of the trap
- Location
- How much waste is inside
Many companies offer monthly or quarterly service plans to help save money over time.
What Happens to the Waste?
Grease trap waste is not just thrown in the trash. It must be taken to a licensed disposal facility. Some companies even recycle the waste into biofuel or other products.

Look for a company that is:
- Licensed and insured
- Has good online reviews
- Offers regular maintenance plans
- Gives you a clear price upfront
- Provides cleaning logs or reports
